Definitions

  • the invention relates to a small contactor according to the preamble of claim 1.
  • a contactor of the kind mentioned is described in document FR-A-1 460 563.
  • Such devices are currently presented in various forms which allow their association with a contactor, either on a front face thereof, or on a lateral face. If a block of auxiliary switches is fixed on the front face of a contactor the depth dimension corresponding to this stacking is increased, and it is then not possible to use this association in boxes, such as those used for domestic equipment, the dimensions of which, once fitted, must not exceed a standardized dimension.
  • auxiliary switches If a block of auxiliary switches is fixed on a lateral face perpendicular to the rows of connection terminals, it is no longer possible to place two contactors side by side, respecting a regular layout because an interval, corresponding to the width of the block, will separate two neighboring contactors.
  • the invention therefore proposes to provide an auxiliary switch device which is capable of not increasing the overall width or the overall depth of a particular contactor with which it is associated.
  • switchgear is not often encountered in which a row of connection terminals relating to auxiliary switches is placed behind the row of connection terminals for the main contacts of the contactor, since the conductor strip leading to the terminals of the main contacts is often seen as an obstacle to the installation, connection and fixing of the auxiliary switch block.
  • the targeted result is achieved thanks to the use of the characteristics presented in claim 1.
  • a small contactor 1 for which the auxiliary contact device 2 of the invention is intended comprises a body 3 having a flat side face 4 comprised between a plurality of parallel isolation partitions 5 serving to separate power terminals 6 aligned in row 16 in a plane Q along an axis XX ′ parallel to this face and a sole 8 serving for its attachment to a support 9.
  • this lateral face 4 is a face superior.
  • This side face has an oblong opening 10 behind which moves, parallel to it, a moving part of the electromagnet 11 of the contactor which is for example provided with a hole or a notch or a coupling groove 12 see FIG. 2.
  • the sub-assembly of auxiliary switches 2 which is mechanically associated with the contactor comprises, see FIGS. 1 and 3, a housing 13 of prismatic shape which mainly has a planar association face 14 which is applied against the face lateral 4, a row 15 of auxiliary switch terminals 18, a coupling finger 17 able to cooperate with the notch 12 suitable and centering and fixing means which will be described below.
  • the row of auxiliary terminals 15 is placed parallel to the row 16 of power terminals when the housing fixed to the body 3 is in another plane P.
  • Centering means which allow give the housing a very precise position relative to the body are constituted by two projecting parallel wings 19, 20 of the housing which penetrate into two parallel grooves 21, 22 of the body 3, the latter being arranged on two opposite lateral faces 23, 24 which are perpendicular to and leading to the upper side face 4, see Figures 1 and 2.
  • the means for fixing the housing to the body comprise on the one hand pins 25, 26 which are placed at one end 27 of the housing and which engage in notches 28, 29 of the body 3 placed on or in the vicinity of the sole 8 and on the other hand, elastic hooks 30, 31 which are placed at an opposite end 36 and which cooperate with the flanges 32, 33 placed in the vicinity of the isolation partitions 5; in a preferred embodiment, the notches 28, 29 are placed in the vicinity of the fixing holes 34, 35 of the sole 8 and between these and the flanges 32, 33 are placed on two opposite external partitions 5 'respectively 5 ", see figures 2, 3 and 4.
  • the housing is attached to the body, see FIGS. 2, 5a and 5b, by first presenting the end 27 in the vicinity of the sole 8 to establish pivoting cooperation between the pins 25, 26 and the notches 28 , 29 and then folding back, in the direction of the arrow G, the opposite end 36 which pivots around the axis ZZ 'passing through the notches towards the isolation partitions 5 and until it is snap-fitted with the partitions 5 'and 5 ".
  • the housing 2 of the sub-assembly of auxiliary switches comprises a cover 59 and a half-housing 62 which has a substantially central partition 37 which is parallel to the association face 14 and which divides the housing into a first open external volume 47 receiving the auxiliary terminals 18 and in a second closed internal volume 38 in which are arranged: two movable contact bridges 39, 40 able to cooperate with two pairs of fixed contacts 41 respectively 42, a control slide 43 able to move the bridges contact, contact pressure springs 44, 45 which are respectively associated with each contact bridge, and a return spring 46 which gives the drawer 43 a rest position, see FIGS. 6, 7 and 8.
  • the fixed contacts are worn by parallel and reversible conductive parts such as 48 which pass through the central partition 37 in such a way that the pads of the fixed contacts (and therefore subsequently the pads of the contact bridges mo biles) are placed in the same plane RR 'parallel to said partition.
  • the control slide 43 is used to actuate auxiliary switches with closing F or auxiliary switches with opening O.
  • contact bridges such as 40, as well as pressure springs 45, are housed respectively in each of two parallel frames 49, 50 placed at opposite ends 51, 52 and drawer 43, on either side of 'a central cavity 53 of axis YY'; these bridges are therefore in the plane SS 'visible in FIG. 7.
  • This cavity 53 comes out to receive a movable end of a weak return spring 46 whose other end, fixed, will rest on a wall 68 of the half -box 62, see Figures 8 and 9 and its outer surface 73 will be used to operate the guide of the drawer, as specified below.
  • Such contact bridges having the function F move, when the drawer is associated with the half-housing, in a first region 54 placed between the fixed contacts 42 and the end 36 of the housing.
  • contact bridges such as 39 and pressure springs 44 are placed, after reversal, in a second region 55 of the volume 38 which is located between the fixed contacts 41 turned over and a bottom 56 constituting the end 27 .
  • auxiliary switches 2 can be fitted either with two switches F or 0, or with an F and an O.
  • the drawer 43 has a partition 67 of generally flat shape having on one face 69 an actuating finger 17 and on the other opposite face 70 the two frames 49, 50, the cavity 53 and two partitions 66, 65 parallel to the axis YY 'and located on either side of the cavity, see Figures 8, 9 and 6.
  • the outer surface 73 of the cavity is guided between two ribs 63, 64 parallel to YY 'which are arranged on the partition 37. These partitions 66, 65 and ribs 63, 64 create baffles which contribute to the isolation of the two switches.
  • the frames 49, 50 are each comprised between upper crosspieces 49 ', respectively 50' placed in the region 71 of the drawer which has the cavity and lower crosspieces 49 ", respectively 50" which are extended respectively by two wings 57-58, 57'-58 '.
  • a movable contact 40 of type F switch is guided in a frame 50, the pressure spring then being supported on an upper cross member 50 'and the contact bridge 40 coming to bear on a lower cross member 50 ", while a movable bridge contact 39 of type 0 switch bears on an opposite side of the lower cross member 49 "under the effect of a pressure spring 44 placed between this contact bridge and the bottom 56; wings such as 57, 57 'and 58, 58' serve to guide such a contact bridge laterally, see FIGS. 8 and 9.
  • a cover 59 which has an oblong opening 60 for delivering passage to the actuating finger 17, could carry the elastic hooks 30, 31 and the guide wings 19, 20, in view, on the one hand, of having only slight dispersions of dimensions and, on the other hand, to be made of a material compatible with the elastic functions of the hooks.
  • thermo-plastic material All the elements of this sub-assembly 2 will advantageously be made by molding a thermo-plastic material, using those of them which are more particularly suitable for obtaining good electrical insulation and respectively for obtaining an elasticity compatible with the function of the hooks.
